All RV's charge the house batteries from the converter.
Some RV's charge the chassis batteries from the converter.
The only way to tell if your RV charges the chassis batteries from the converter is to check, either with a VOM, or by manufacturer documentation.

WHOA! Rv power source is NOT the same wiring as a household range! Good advice to look up the correct wiring diagram. 240 volts could fry your electronics. 50 amp RV service is two separate 120v legs. No problem to use adapters and step down to a 15 or 20 amp household plug to charge batteries.
This is precisely, 100% wrong.
Both the 50 amp RV outlets and the 4 prong range outlets are wired:
1: L1
2: L2
3: NEUTRAL
4: GROUND
From L1 to NEUTRAL or GROUND is 120v.
From L2 to NEUTRAL or GROUND is 120v.
From L1 to L2 is 240v.
From NEUTRAL to GROUND is 0v.
On both types of circuits.
